It's the same as how Congress's approval rate is extremely low, yet in the last election most seats didn't change hands. In both cases, people are saying "everyone else is the problem, not me!" -- they said "vote out your incumbents" but still voted for their incumbents claiming their incumbent isn't the problem.
What makes this complicated is that I think that's a reflection of America. My congressman _is_ a really good representative for me: he's a smart gay liberal who has started several successful tech companies. I vote for him because he's doing stuff I like. My aunt's congressman is a good representative for her: a pro-life, pro-gun conservative creationist pastor. She votes for him because he's doing stuff she likes. We'd like to think that there's a logical disconnect between "congress is crazy" and "my congress person is awesome" but that's not necessarily true: we, as a country, have an extremely wide spectrum of opinion. Jim Hightower used to say there's nothing in the middle of the road but yellow stripes and dead armadillos. If congress is a dead armadillo, midway between what I want them to be and my aunt wants them to be, my aunt and I can both be contemptuous of congress while liking our personal representatives, and both of us can be logically consistent in doing so.
Lactose intolerance is complex. The Tuareg of Saharan Africa have lower lactose intolerance rates than Finnish people, for instance. It mostly has to do with whether a group has spent a long time as nomadic herders or not, and adult persistence of lactase activity appears to be caused by several different mutations, that arose spontaneously. http://s1.zetaboards.com/anthr... has a nice list of adult lactase activity in different ethnic groups.
There was a fairly interesting Radiolab podcast about a program that shipped New York City's biosolids to Colorado for use as fertilizer: http://www.radiolab.org/story/... It includes a significant discussion of waste treatment, pathogens, and the economics of shipping what some municipalities call hazardous waste cross-country.
Pure speculation, but it could very well be a knock-on effect from off-shoring manufacturing. You want at least some of your engineers to be close to the manufacturing line to debug when things go wrong. The designers might stay in the US, but manufacturing, test, packaging, etc., will shift towards the factories. And then, some years later, you'll want the designers to be near the mfg/tst/pkg guys to allow easier communication.
It's exactly this. You want your chip designers to be working right next to the mask layout people because layout needs designers to correctly optimize the layout. You want your test people to be able to walk through the whole test program design with the designers, who will be involved throughout the test hardware and program design, because test engineers know how testers work, and designers know how the chip works, and matching those is tricky. And you don't really want to be shipping tested wafers overseas for packaging and then waiting for them to come back to test packaged parts, and the product engineers need tester access and parts access to characterize the parts and produce the datasheet info, so at that point you have the whole silicon design team, from conception to finished parts, in one place. It can be done remotely but with a significant time adder or lots of evening/midnight phone meetings. It's easier to separate applications and project engineering from the design/manufacture group, but there's still some value in having them colocated. At that point, all that's left is middle management... and that's even easier to outsource.
If private organizations can't use drones to help with natural disasters, such as those in Colorado, how do you suppose this will get approved to fly near local airports and various cities and towns won't outlaw the flying of drones?
Of course, there's always the question: How do you deliver to high-rise apartments and other high-density dwellings?
During the Colorado flood, the area around it was under temporary flight restrictions, as determined by the FAA, and no unauthorized aircraft were allowed to fly in it. While TFR's are getting vastly more common as every penny-ante promoter wants to make every event seem so big it needs special FAA protection to allow it to run, the reality is that 99% of the time, 99% of the airspace is available for private and commercial air operations.
If anything, I'd mistrust the people who make a big deal about never looking at internet porn. Just look at the frequent revelations involving vocal evangelists.
In general, I've come to the conclusion the louder someone screeches about the morality of other people, the higher the likelihood they'll get caught in a scandal.
Which has more or less confirmed for me that people are lying douchebags, who mostly want to point the finger at everyone else.
The more rigid and extreme the position, the more they're full of shit.
While I entirely agree with your position, something to consider is that there is a logically consistent stance embedded in there. If you believe that everyone is a sinner and should try to reduce the amount that they sin, then it's consistent to sin while being vocally opposed to sinning: the person may regret the behavior and pray for forgiveness and all those other weird things people to do try to make themselves feel better about natural impulses that their churches have told them are bad. I think that situation is practically universal among evangelical religious types of most religions. They're all trying to force themselves and everyone else to hold high standards of living, and while failures to do so are inevitable they're still bad.
Sure it doesn't do what a good logic analyzer does, but it's fast. Current project: trying to get an Ohaus digital scale's RS232 output talking via an FTDI serial-to-usb to my computer. Scope-to-computer works great. Computer-to-scope doesn't work at all. Hook up probes to the TX and RX lines and I can immediately see that something's going from minicom to the Ohaus, and the voltage is roughly what I'd expect. On RS232 that's a serious question, and one that most of the usb logic analyzers I've worked with don't address: is the voltage high enough to trigger something that may be expecting 12 volts? And I'd like to see what it's actually sending. Hit the trigger button and type something in, and there it is on the screen. Save it, type in something else, overlay them. Hey, the FTDI is stripping off the terminal linefeed! That's good to know, given that the Ohaus absolutely requires CR,LF. That took me about thirty seconds with a scope. It'd take me longer to start up the USB logic analyzer program and get it set up.
Another advantage, if purchasers care to implement it, is that you can have somewhat intelligent LED lights that dim down to 30% when there's no traffic around, so it's still light, but much lower power, then run back up when traffic is a block away. It doesn't add much to the system cost to add motion detection and communication with nearby lights, particularly since some industrial/commercial LED lights are adding selftest health/failure reporting already.
I work in south Longmont. Where I cross the Boulder Creek, it's usually 3 meters wide and so shallow the rocks on the bottom emerge from the surface of the water. When I was hauling out yesterday after our workplace got an evacuation notice, the creek was a kilometer wide, backed up against the bridge, which is probably 15 meters wide by two meters deep. Longmont spent eighteen months reworking the Lefthand Creek drainage, deepening it and tearing out all the trees beside it, through the middle of the city. At the time, local citizens were outraged at the expense, writing nasty letters to the newspaper and showing up at city council meetings yelling about what a waste of money it was and how debit spending was the devil. Lefthand filled right up to the top and moved like a freight train, but didn't overtop through much of the town. The place where they stopped the rework, and the creek returns to its shallow, cottonwood-tree-filled drainage, is where it spread out and started flooding basements, according to pictures my friends who live there are sending me. I'm hoping this experience will motivate the city of Boulder to do the same for Boulder Creek. One of my friends lived in a house across from Naropa University, right beside Boulder Creek, that had a big metal sign on the front warning the inhabitants that they lived in a flood zone. That should never happen. That should be parkland, not places where kids live. (She moved, thankfully, because that house had close to two meters of water in the main floor, from pictures I've seen, and I'd hate for her and her two toddlers to still be living there.)
fructose is just a disaccharide, its technically a more complex carb chain than glucose (monosaccharide). do you mean high fructose corn syrup? you're sort of right. typically what you see is HFCS55 which is 55% fructose and 41% glucose. to put it in perspective, granulated sugar is 50/50 fructose/glucose. so HFCS is only marginally more fructose than regular sugar, so you're wrong. but you're also right, because sugar, hfcs and all the other high glycemic carbs are what's really causing this problem.
LOL indeed. Fructose is a monosaccharide: http://en.wikipedia.org/wiki/Fructose "Fructose, or fruit sugar, is a simple monosaccharide" just like glucose. They're isomers of each other. Sucrose is a disaccharide, consisting of a glucose and a fructose, 50% of each. http://en.wikipedia.org/wiki/Sucrose "The molecule is a disaccharide composed of the monosaccharides glucose and fructose" Sheesh.
I think it's the 'lol' that particularly annoys me when people say things that are just flat-out wrong.
Just wondering: are 150 years projects viable at all? Is there any example of such an enterprise? What's the incentive for human beings to take part in thigs they won't see the results of?
The Second Avenue Subway project in New York City was started in 1929. It's expected to be partially open in 2016. http://en.wikipedia.org/wiki/Second_Avenue_Subway The Great Wall Of China has seen nearly continuous work and improvement over 1500 years. There are a number of Japanese temples that have periodic maintenance/reconstruction schedules that have been running continuously for 500 years.
Sorry about the delay in replying. Those are some pretty awesome caps for railgun/coilgun/quartershrinker applications. High voltage, high amperage capability. If you decide to play with this, bolt a 1 meg resistor across the cap leads and leave it there all the time that they're not actually installed in working equipment, because this stuff could kill you with a discharge. So, yeah, rated voltage and, if they list it, equivalent series resistance, which is a measure of how quickly it can discharge, and you'd like as small as possible.
A rifle? Catch Doc Brown next time he stops over in 2013. Maybe he has an extra Mr. Fusion to spare. If you throw that in a backpack, maybe you can power your handheld rifle for a few shots.
Can anyone explain why they would/wouldn't work? I'm fairly newbish when it comes to the intricacies of electronics, and trying my best to develop a healthy understanding.
A non-inclusive answer is that the energy stored in a capacitor rises with the square of the voltage, so what you want for really high energy density is very high voltage caps. But, along with that, when you discharge them, you're relying on an extremely quick discharge so you get huge amounts of amperage out of them (discharge current = voltage / time) so you also need massive current-carrying capability for the plates and wiring. That means fairly specialized capacitors.
A horse can do a large amount of work, they are more useful on the yoke than on the table. Same with dog. Dogs are more useful as a work animal than a food animal. Cows, not so much. I can't think of too many situations where a cow would be best suited as a work animal.
Until the invention of the yoke, in about 400 AD, and its propagation to Europe in about 1000 AD, horses were nearly useless as draft animals. They're still less useful for ploughing and cart-pulling than oxen are in hot parasite-ridden countries because they're more delicate.
Most of the medical professionals and vetrinarians in my area of southwest Utah know about it.
It's no secret.
People gotta live somewhere. Fires, floods, earthquakes, malaria, congressmen, natural radiation, natural heavy metals in ground water... every place has some problem.
It isn't like we are talking about bubonic plague running rampant. What should the government do? Spray bleach over everything? Kick people off their own property?
Funny you mention that: the bubonic plague is endemic throughout the American southwest and there are reported cases in people every year. Prairie dogs, among other rodents, carry it. (Most common cause of infection is outdoor cats getting plague-infected fleas that have left dead prairie dogs, then bringing the disease home to their owners.)
And as for the where-should-we-live, I made a map of natural disasters in the US a while ago when people were on about how anyone would be dumb enough to live in Norman, Oklahoma. Between hurricanes, tornadoes, earthquakes, tidal waves, forest fires, flash floods, bubonic plague, volcanoes, and a couple of other things, the only place I've found that looks fairly safe in the entire US is somewhat east of Pocatello, Idaho.
If the expense/time is a bit daunting, mosquitoes are attracted to heat, so some incandescent bulbs in front of a fan, with a mesh bag behind it, will scoop them out of the air (along with lots of other insects.) I had a friend with one of these and she collected something like a pound of insects per night. With that said, I don't think either one is going to make a dent in your local mosquito population unless you had two dozen of them running nonstop. Getting rid of stagnant water in your neighborhood will do far more than any amount of adult mosquito hunting.
Edward Murphy proposed using electronic strain gauges attached to the restraining clamps of Stapp's harness to measure the force exerted on them by his rapid deceleration. Murphy was engaged in supporting similar research using high speed centrifuges to generate g-forces. Murphy's assistant wired the harness, and a trial was run using a chimpanzee.
The sensors provided a zero reading; however, it became apparent that they had been installed incorrectly, with each sensor wired backwards. It was at this point that a disgusted Murphy made his pronouncement
So this is potentially, very much related to the original usage.
If I remember right, the way a wheatstone strain gauge is set up, there are four ways to connect it. One is right, two are wrong but give you half the resolution you expected -- so you get data, just lousy data -- and one is completely wrong and you get no data whatsoever. It was hooked up in the completely wrong configuration. That was what made him so mad: there was only a 25% chance it would get hooked up in the completely worthless configuration, but that's what happened.
You'd be better off trying to get Shakesphere out of schools for his anti-Jewish views - those *did* get expressed in his plays.
Slashdot isn't the place for a deep discussion of Shakespeare, but I'm going to, anyway. It's arguable (and is regularly argued) that Shakespeare was not actually anti-Semitic. Shylock is portrayed as a villain, it's true, but his speech, "I am a Jew. Hath not a Jew eyes? Hath not a Jew hands, organs, dimensions, senses, affections, passions; fed with the same food, hurt with the same weapons, subject to the same diseases, healed by the same means, warmed and cooled by the same winter and summer as a Christian is?" shows him (at least in that passage) as a sympathetic human, not a villain, and more generally, the rest of the speech, where he declares that he'll act just as horribly as his persecutors do (and proceeds to do so, driving the play) can be seen as a character's reaction to a bigoted society, rather than of the author's hatred of Jews. Shakespeare had some outright villains who did evil just to do evil, but generally his worst characters (and I'm thinking of Iago and Shylock specifically) had excellent, rational motivations for doing the evil things they did. His writing of them was not based on hatred of their races, but on how society had shaped them into tools for evil.
I have a machine shop in my garage, which includes a large mill and a lathe. Both have lead screws set to work in thousands of an inch, so one revolution of a handle is a certain subset of inches (.05) with individual tick marks at.001. It is essentially baked into the hardware, and you have to replace the feed wheel dials and lead screws to change it, among other things.
As a fellow machinist, I put a DRO on my lathe and a CNC controller on my mill. Now I hit a button and everything displays in metric. It's very nice, especially when I can have the mill machine ellipses while I'm busy using the lathe.
It depends. There's "autistic", where (and I'm not trying to be insensitive with my description, here) someone may be wearing protective gear, rocking/spinning, groaning a lot and freak out if there is any noise or light and who are literally unable to communicate with their family in any manner beyond gesturing . . . and then there are the Slashdot hipsters who have taken to the trend of self-diagnosing with Asperger's over the last five years, because they are occasionally "socially awkward penguin" or "are really obsessive about something and detail oriented".
The article makes it pretty clear that they're talking about "socially awkward" Asperger's people (presumably legitimately so and not those climbing on board the label, because they took an online quiz) and not the ones who have actual communication issues and have difficulty functioning within their home, much less in a professional environment performing QA functions.
I have friends who have autistic children, so I really hope my description of the first case isn't made out to be cruel. In my (limited, as an outsider) experience, it is pretty accurate of the lower ends of the Autism spectrum.
There are also people who move across that continuum. My wife has a lot of classical physical autism characteristics: rocking/spinning, inability to function with noise or bright/flashing lights, finds the touch of silk, moving water, grass completely unbearable, walks on her toes all the time, among others, but can usually manage to work a real job that involves dealing with problem children for eight hours a day because she has worked out a very precise, detailed system of how she approaches the work, and she's fantastically good at what she does. If an employer is willing to go to the effort to provide the specific work environment in which a borderline autistic person can function, it could be hugely beneficial for both the employer and the employee.
I'm starting my tomatoes under 10 Cree LED's mounted to a heatsink, with water-cooling on the heatsink running through a copper pipe in the water beneath the starts, so they get both light and heat. They're doing fine so far, is the best I can say: growing faster than last year's starts, which were getting full sun but no heat, whereas these are getting very indirect sun but 14 hours of LED per day. Because I'm a geek I have an arduino measuring/recording the temp of the LED heatsink, the water beneath the plants, and checking a realtime clock to decide when to turn things on and off, with control over the LED dimming (for overtemp) and pump speed (likewise). The Crees are cool white, putting out about 50 lumens each, which is a meaningless measure for growlights, but useful for comparison, I guess. Tomato starts at the edge of the array are growing much more slowly than the ones right under the lights (the LED's are packed all in one small array) so since the whole works is at the same temp, I presume that means the ones in the center are strongly benefitting from the LED light. If I did it again, I'd make an array that was planar rather than packed in at one point, for growing in a downstairs space with only small windows, but I'd stick with the single block of LED's for what I typically do, with them sitting in a south-facing window upstairs.
"Cain expressly has his own wife, though its not entirely clear where she came from,"
I am from the deep south and this is what my great aunt told me years ago, about Cain's wife. After Cain killed Abel, he was exiled to Ur. The only thing in Ur to mate with was monkeys. Black people came from Cain & a monkey. No lie. That's what my great aunt believed, which is not to say I believe it.
I'm not saying your grandmother was any more wrong than anyone else citing the bible for their beliefs, but a much more widespread belief is that black people were the descendents of Ham. Since Ham was cursed for the misfortune of having seen his father Noah naked, his offspring were also all cursed, which was used as an excuse for treating black people as second-class citizens or excusing slavery. http://en.wikipedia.org/wiki/Curse_of_Ham
Another competing theory for the wives of the sons of Adam was angels or other semi-divine creatures.
While you might not be able to buy any complete laser pointer over 5mW, you certainly can buy laser _modules_ waaaaaay over that. I've bought a 100mW red and a 200mW blue for use in CNC cutting from ebay. They shipped from Hong Kong and arrived here with no hassle. I'm about to get a 1.5 watt diode module. (Note to anyone thinking about this: buy a good set of goggles appropriate for the frequency of the laser you want, and _test_ it with a lower-power laser, by shining the lower-power laser through the goggles and measuring the reduction in intensity by, say, measuring the current coming out of a coin-sized solar cell as compared to direct illumination. That'll at least give you some idea you didn't buy junk. Also buy a whole module with glass lenses: trying to make your own optics system with a bare diode pressed into a heatsink and a separate fast axis/collimation lens is a waste of time. You can build your own supply using an LED driver chip, if you don't want the heat associated with typical cheap linear laser diode drivers.)

Until the invention of the yoke, in about 400 AD, and its propagation to Europe in about 1000 AD, horses were nearly useless as draft animals. They're still less useful for ploughing and cart-pulling than oxen are in hot parasite-ridden countries because they're more delicate.
Most of the medical professionals and vetrinarians in my area of southwest Utah know about it.
It's no secret.
People gotta live somewhere. Fires, floods, earthquakes, malaria, congressmen, natural radiation, natural heavy metals in ground water... every place has some problem.
It isn't like we are talking about bubonic plague running rampant. What should the government do? Spray bleach over everything? Kick people off their own property?
Funny you mention that: the bubonic plague is endemic throughout the American southwest and there are reported cases in people every year. Prairie dogs, among other rodents, carry it. (Most common cause of infection is outdoor cats getting plague-infected fleas that have left dead prairie dogs, then bringing the disease home to their owners.)
And as for the where-should-we-live, I made a map of natural disasters in the US a while ago when people were on about how anyone would be dumb enough to live in Norman, Oklahoma. Between hurricanes, tornadoes, earthquakes, tidal waves, forest fires, flash floods, bubonic plague, volcanoes, and a couple of other things, the only place I've found that looks fairly safe in the entire US is somewhat east of Pocatello, Idaho.
I really want to build a laser mosquito zapper (like this one: http://spectrum.ieee.org/consumer-electronics/gadgets/backyard-star-wars). However, this looks pretty pricey (multiple cameras and galvanometers).
If the expense/time is a bit daunting, mosquitoes are attracted to heat, so some incandescent bulbs in front of a fan, with a mesh bag behind it, will scoop them out of the air (along with lots of other insects.) I had a friend with one of these and she collected something like a pound of insects per night.
With that said, I don't think either one is going to make a dent in your local mosquito population unless you had two dozen of them running nonstop. Getting rid of stagnant water in your neighborhood will do far more than any amount of adult mosquito hunting.
Amusingly, when someone actually attempted to track down who murphy was, and where the law came from.... http://en.wikipedia.org/wiki/Murphys_law
So this is potentially, very much related to the original usage.
If I remember right, the way a wheatstone strain gauge is set up, there are four ways to connect it. One is right, two are wrong but give you half the resolution you expected -- so you get data, just lousy data -- and one is completely wrong and you get no data whatsoever. It was hooked up in the completely wrong configuration. That was what made him so mad: there was only a 25% chance it would get hooked up in the completely worthless configuration, but that's what happened.
You'd be better off trying to get Shakesphere out of schools for his anti-Jewish views - those *did* get expressed in his plays.
Slashdot isn't the place for a deep discussion of Shakespeare, but I'm going to, anyway. It's arguable (and is regularly argued) that Shakespeare was not actually anti-Semitic. Shylock is portrayed as a villain, it's true, but his speech, "I am a Jew. Hath not a Jew eyes? Hath not a Jew hands, organs, dimensions, senses, affections, passions; fed with the same food, hurt with the same weapons, subject to the same diseases, healed by the same means, warmed and cooled by the same winter and summer as a Christian is?" shows him (at least in that passage) as a sympathetic human, not a villain, and more generally, the rest of the speech, where he declares that he'll act just as horribly as his persecutors do (and proceeds to do so, driving the play) can be seen as a character's reaction to a bigoted society, rather than of the author's hatred of Jews. Shakespeare had some outright villains who did evil just to do evil, but generally his worst characters (and I'm thinking of Iago and Shylock specifically) had excellent, rational motivations for doing the evil things they did. His writing of them was not based on hatred of their races, but on how society had shaped them into tools for evil.
I have a machine shop in my garage, which includes a large mill and a lathe. Both have lead screws set to work in thousands of an inch, so one revolution of a handle is a certain subset of inches (.05) with individual tick marks at .001. It is essentially baked into the hardware, and you have to replace the feed wheel dials and lead screws to change it, among other things.
As a fellow machinist, I put a DRO on my lathe and a CNC controller on my mill. Now I hit a button and everything displays in metric. It's very nice, especially when I can have the mill machine ellipses while I'm busy using the lathe.
It depends. There's "autistic", where (and I'm not trying to be insensitive with my description, here) someone may be wearing protective gear, rocking/spinning, groaning a lot and freak out if there is any noise or light and who are literally unable to communicate with their family in any manner beyond gesturing . . . and then there are the Slashdot hipsters who have taken to the trend of self-diagnosing with Asperger's over the last five years, because they are occasionally "socially awkward penguin" or "are really obsessive about something and detail oriented".
The article makes it pretty clear that they're talking about "socially awkward" Asperger's people (presumably legitimately so and not those climbing on board the label, because they took an online quiz) and not the ones who have actual communication issues and have difficulty functioning within their home, much less in a professional environment performing QA functions.
I have friends who have autistic children, so I really hope my description of the first case isn't made out to be cruel. In my (limited, as an outsider) experience, it is pretty accurate of the lower ends of the Autism spectrum.
There are also people who move across that continuum. My wife has a lot of classical physical autism characteristics: rocking/spinning, inability to function with noise or bright/flashing lights, finds the touch of silk, moving water, grass completely unbearable, walks on her toes all the time, among others, but can usually manage to work a real job that involves dealing with problem children for eight hours a day because she has worked out a very precise, detailed system of how she approaches the work, and she's fantastically good at what she does. If an employer is willing to go to the effort to provide the specific work environment in which a borderline autistic person can function, it could be hugely beneficial for both the employer and the employee.
I'm starting my tomatoes under 10 Cree LED's mounted to a heatsink, with water-cooling on the heatsink running through a copper pipe in the water beneath the starts, so they get both light and heat. They're doing fine so far, is the best I can say: growing faster than last year's starts, which were getting full sun but no heat, whereas these are getting very indirect sun but 14 hours of LED per day. Because I'm a geek I have an arduino measuring/recording the temp of the LED heatsink, the water beneath the plants, and checking a realtime clock to decide when to turn things on and off, with control over the LED dimming (for overtemp) and pump speed (likewise). The Crees are cool white, putting out about 50 lumens each, which is a meaningless measure for growlights, but useful for comparison, I guess. Tomato starts at the edge of the array are growing much more slowly than the ones right under the lights (the LED's are packed all in one small array) so since the whole works is at the same temp, I presume that means the ones in the center are strongly benefitting from the LED light. If I did it again, I'd make an array that was planar rather than packed in at one point, for growing in a downstairs space with only small windows, but I'd stick with the single block of LED's for what I typically do, with them sitting in a south-facing window upstairs.
"Cain expressly has his own wife, though its not entirely clear where she came from,"
I am from the deep south and this is what my great aunt told me years ago, about Cain's wife. After Cain killed Abel, he was exiled to Ur. The only thing in Ur to mate with was monkeys. Black people came from Cain & a monkey. No lie. That's what my great aunt believed, which is not to say I believe it.
I'm not saying your grandmother was any more wrong than anyone else citing the bible for their beliefs, but a much more widespread belief is that black people were the descendents of Ham. Since Ham was cursed for the misfortune of having seen his father Noah naked, his offspring were also all cursed, which was used as an excuse for treating black people as second-class citizens or excusing slavery. http://en.wikipedia.org/wiki/Curse_of_Ham
Another competing theory for the wives of the sons of Adam was angels or other semi-divine creatures.
You can't import anything into the US over 5mW.
While you might not be able to buy any complete laser pointer over 5mW, you certainly can buy laser _modules_ waaaaaay over that. I've bought a 100mW red and a 200mW blue for use in CNC cutting from ebay. They shipped from Hong Kong and arrived here with no hassle. I'm about to get a 1.5 watt diode module. (Note to anyone thinking about this: buy a good set of goggles appropriate for the frequency of the laser you want, and _test_ it with a lower-power laser, by shining the lower-power laser through the goggles and measuring the reduction in intensity by, say, measuring the current coming out of a coin-sized solar cell as compared to direct illumination. That'll at least give you some idea you didn't buy junk. Also buy a whole module with glass lenses: trying to make your own optics system with a bare diode pressed into a heatsink and a separate fast axis/collimation lens is a waste of time. You can build your own supply using an LED driver chip, if you don't want the heat associated with typical cheap linear laser diode drivers.)
